I noticed on the Princess website it states you can save 20% if you buy the card before your cruise. Am I correct in thinking that is basically the gratuity? If you bought it on the ship, you would pay gratuity?

Does anyone know if golf carts can be rented to get around Victoria from the cruise ship pier? I have very bad knees and would like to see downtown with a little freedom. I know their are electric bikes and scooters for rent, but would really like a golf cart type thing. Thanks!
